Set current release line

Alter ETA calculation to use the rate over the past 30 seconds instead of over the whole transfer, and allow that 30 second window to be adjusted.

-Introduction
-************
-
-This is the README for `pv' ("Pipe Viewer"), a terminal-based tool for
-monitoring the progress of data through a pipeline.  It can be inserted into
-any normal pipeline between two processes to give a visual indication of how
-quickly data is passing through, how long it has taken, how near to
-completion it is, and an estimate of how long it will be until completion.
-
-
-Documentation
-*************
-
-A manual page is included in this distribution.  See `man ./doc/quickref.1',
-or `man pv' after installation.
-
-
-Compilation
-***********
-
-If this is not a packaged release, first run "./generate.sh".
-
-To compile the package, type "sh ./configure", which should generate a
-Makefile for your system.  You may then type "make" to build everything.
-Note that GNU `make' is required; this may be installed as `gmake' on some
-systems, so if typing "make" gives an error, try "gmake" instead.
-
-See the file `doc/INSTALL' for more about the `configure' script.
-
-Developers note that you can do "./configure --enable-debugging" to cause
-debugging support to be built in, and "--enable-profiling" builds in
-profiling support (see "man gprof").  Also note that doing "make index" will
-generate an HTML code index (using "ctags" and "cproto"); this index lists
-all files used, all functions defined, and all TODOs marked in the code.

-* Sun Sep  5 2021 Andrew Wood <andrew.wood@ivarch.com> 1.6.19-1
-- fix: starting pv in the background no longer immediately stops unless
-- the transfer is to/from the terminal (Andriy Gapon, Jonathan Elchison)
-- fix: using -B, -A, or -T now switches on -C implicitly
-- (Johannes Gerer, André Stapf)
-- fix: AIX build fixes (Peter Korsgaard)
-- i18n: updated German "--help" translations (Richard Fonfara)
-- i18n: switched to UTF-8 encoding, added missing translations (de,fr,pt)
-- docs: new "common switches" manual section (Jacek Wielemborek)
-- docs: use placeholder instead of /dev/sda in the manual (Pranav Peshwe)
-- docs: mention MacOS pipes and "-B 1024" in the manual (Jan Venekamp)
-- docs: correct shell in autoconf/scripts/index.sh  (Juan Picca)

-- (r162) (#1532) fix target buffer size (-B) being ignored (AndCycle, Ilya
-- Basin, Antoine Beaupré)
-- (r164) cap read/write sizes, and check elapsed time during read/write
-- cycles, to avoid display hangs with large buffers or slow media; also
-- remove select() call from repeated_write function as it slows the
-- transfer down and the wrapping alarm() means it is unnecessary
-- (r169) (#1477) use alternate form for transfer counter, such that 13GB
-- is shown as 13.0GB so it's the same width as 13.1GB (André Stapf)
-- (r171) cleanup: units corrections in man page, of the form kb -> KiB
-- (r175) report error in "-d" if process fd directory is unreadable, or if
-- process disappears before we start the main loop (Jacek Wielemborek)
